Uncaught Exception is when you throw an error and did not catch anywhere.

Unhandled promise rejection is similar, when you fail to catch a Promise.reject.

It's about whether the error was generated by throw or by Promise.reject (more like error generate from sync vs async process/code). Note that throw inside an async function is Promise.reject as async functions are wrapped inside Promise for you
